Fluorescent Dye

Fluorescence is a phenomenon of photoluminescence in luminescence. When an atom is irradiated by light, some electrons around the nucleus jump from their original orbitals to higher energy orbitals under the influence of light energy, i.e., from the ground state to the first or second excited single-line state, etc. Due to the instability of the first or second excited singlet state, the electron returns from the excited singlet state to the ground state accompanied by released energy, resulting in fluorescence.

Fluorescent dyes can be covalently bound or physically adsorbed in the structure of the substance. The fluorescence properties allow for the characterization, localization and quantitative analysis of the labeled object. Fluorescent dyes have shown great potential for the detection of proteins, nucleic acids, cells, and immunoassays, attributed to the advantages in non-radioactive contamination, simple experimental operation and easy observation.

Fluorescent dyes have penetrated many fields such as pharmacology, physiology, environmental science, and information science, as well as functional studies of proteins and drug screening.

    Dns–LLC
    Dns-LLC is a cell-permeable Cu+-selective fluorescent probe that forms a 1:1 complex with Cu+. The thiol group of Dns-LLC plays a key binding role, while the sulfonamide and amide groups jointly contribute to the stabilization of the complex. Upon binding to Cu+ in aqueous buffer solutions, Dns-LLC generates a turn-on fluorescence response, which can be used for the detection of Cu+ in the Golgi apparatus.
